I have always thought that the T30 Roadbuster toy was just okay. I appreciate the integration of modular weapons, and his transformation is easy and fun. However, I felt (and still do) that the arms were spindly and overly long, and everything south of his knees should be a page one rewrite. His alt mode is okay. A decent enough update, but not really the flat, broad, Jeep/Toyota/Humvee/whatever design cues that I associate with him.
For me, the Roadbuster situation is a bit like T30 Jetfire. At the time, T30/LG Jetfire felt like a decent enough place holder for an updated toy. However, the Siege Commander hit all of the notes that I wanted in a true, modern update. I just want a similar update for Roadbuster. Not saying he needs to be a Commander, but I feel like the current team would be capable of cranking out a nice version that homages the original.
TL;DR: It's not a bad toy; it's pretty fun to fiddle with. It just doesn't particularly scratch my itch for a true update to the original toy, which is what I would prefer.
